The present invention has relation to har-l g ness connecters, fand in particular'k to such devices asare designed to attach the vharness cords to the frames of theV harnessesl It has e as Aits objecttoprovide novel and yimpro-ved mea-ns for attaching the harness cords to the frames ofthe harnesses or heddles with ca- Y pa'cityfforquick: and easy detachment and l reattachment ofthe cords to permit removal I and replacement of -"the.harnesses, and also v capacity -for simple,easy, and minutely accurate adjustment of the effective length ofthe cords to remove allslack and keep the n, rigging in tightrelation assuring accuracy in the actnationof the harnesses in their shedding action.y Y. 's 1 Y. y Y j "To'th'e'se ends, theinvention comprises a portion ladapted to be eng-agedfwith the end ofthe cord or 'other harness-supporting and actuating device, and with a screwfherad, but ton or similar'headed projection y'on the harness `frame, the naturegof theco-nnection be.- tween this portion and the headed projection being suchthat disconnection and reconnectioncan be easily effected by a relative lateral movement of thetwo parts. -To prevent 'ace cidental separation. the parts are preferably Y combined so that-disconnection will require first a relative movement of the said portion ofthe connecter towardthe frame and axially-fof lthe projection,;and second, a lateral movementV of this portion at substantially right angles to the lirt direction of movef ment Theunhooking movement thus com; pelled to have components of motion in two directions at right angles toV each lother' is further restricted through confining the lait# eralV movement' to a single plane extending along the axis of the headed projection, lso

use to rotate about'V the aXisof the headed-pro jection, there are only two points-in each revolution 'at which the aforesaid axial fand i lateral movements will'enable the parts to be disconnected. 'In thismanner a method of attaching yand detachs'mg the parts is pro vided which,v while veasily, effected by the'sim# plest of manual operations, is practically impossible `to `'accomplish accidentally i inthe course of the working "ofthe loom'. The inthat while the connecter is designedwh'en'in.

yvention further* comprisesl ythe 'combination with'the novel attaching and detaching provisions' of the well-known turnbucklef means of adjustingtheeffective length of the harness cordsto attain thel desired orpcorrect te'r'1sion."v An illustrative embodiment -of' the invention is shown in the drawings, in which,--4 v Fig. lishowsa portionpof 4a loom, indicating aha'rness fra-meand cord therefor attached tothe lframe through' the'use of the invention.

At 9 is indicated the frame of the harness, usually of Wood, which. is provided with projections 10 extendingupwardlyfrom its upper edge,. (andsimilarly .downwardly from its lower edge,) .characterized by an enlarged portion or head andV a shankhaving'a thin orreduced part between the head and the surface of the frame.: Herein this projection is constituted byva screw driven intothelwood of theframe 2 sothataj halfinch'or soeof its shank v11' is a exposedladjacentthe head The portion liof the connecterwhich engages withthe head of the screwis inthe form of a loop of metal having an axial bore .17 vthrough. .its closed lower-end fitting easily the diameter of the shank 11 of the headed projection or screw.
